METAL BEDSTEAD.

Application filed November 14, '1921. Serial No. 515,110.

T o all whom t may concern Be it known that I, JULES'ARMAND BLIN, a citizen of the French Republic, residing at Paris, France, have `invented new and useful Improvements in Metal Bedsteads, of`

which the following is a specification.

Thisfinvention relates to metal bedsteads preferably of aluminum or its alloys, characterized by the method of construction'of the lower frame and the means provided for ensuring rigidity of said frame by tying and strengthening the two longitudinal members-with the head and foot of the bed con1 stituting the frame, one of these arrange- 16 ments comprising rigid cross pieces and the other comprising cables fitted with tensioning devices. s Two forms of construction forcarrying the invention into effect, are shown, by way 2o of example, in the accompanying drawings:

Figure l1 is a plan 'of the complete arrangement having rigid cross pieces fitted in the lower frame ofthe bedstead; Figs. 2, 3

and 4 show to a larger scale in vertical section respectively on the lines A A, B B and C C of Fig. 1, the manner of constructing the lower frame of the bedstead and the cross pieces; Figs. 5 and 6 show perspective views of the outline of the central cross piece and one of the assembly fittings for this cross piece "on the frame. Figs. 7 and 8 show in perspective the outline of one of the intermediate cross pieces and an assembly fitting therefor; Fig. 9 shows diagrammatically a modified construction wherein the arrange ment consists of cables and tensioning devices. 0 As will be seen from Fig. l of 40 formed of two longitudinal members a suitably connected together with the ends al at head and foot. These longitudinal members consist of two sheets of metal so as to form, when joined together a rectangular section having an external recess a2 (Fig. 2) 0n which can be fitted an ornament as.

The two members a are connected by a central cross member b consisting of twok sheets of metal bent U shape and fitted one upon the other (Fig. 3) so forming a square section. This cross piece terminates at each f 5.5 vOLI the members c are fitted two gussets or the draw-k ing, the lower vframe of the bedstead isr housings c (Fig. 6) whose shape corresponds to that of the'cross piece b and whose two lateralsides are bent inwards to formslide- 4ways 01 for the reception of the wings b1 of the cross piece.

The latter rests on the stops o2 obtained by bending the lower part of each of the gussets 0. f .n

rlhe rigidity of the frame is completed by four intermediate cross pieces d disposed diagonally. Each of these consists of a metal sheet bent' to form an inverted triangular section (Fig. 4) whose apex is extended by two vertical walls d1 bearing against each other and also having two wings d2 (Fig. 7).

rTriangular gussets e (Fig. 8) Vhaving,like the gussets c, slideways el and stops e2 are fixed on the one hand in the angles of a frame formed by the longitudinal members a and by the ends al on each of the posts f ofthebedstead and, on the other hand, on

.the middle part of the central cross piece ZJ so that, when the wings cl2 of the intermediate members d, are engaged inthe slides e1 of these gussetsand the vertical parts d1 resting on the stops e2,'the four cross pieces d form the diagonale of the frame.

It will be clear that this arrangement of a central cross piece connecting the longitudinal members and four intermediate diagonal members, gives an arrangement which ensures the rigidity of the lower frame by reason of the construction of-these cross pieces of light metal such as aluminiumV or its alloys and arranged so that they themselves have great strength.

rFhis'arrangement further provides a great advantage of being able to assemble or dismantlethe parts easily and .very quickly without the necessity of any special tools and Vwhen dismantled, the vconstituent parts take up little room which therefore facilitates transport, packing and storage.

According to the construction shown in Fig. 9 the arrangement comprises, as in the preceding case, a central cross member b connecting the two longitudinal members a. In the central Lpart and on each of the vside members of this cross piece arefitted clips or brackets g, g1 carrying the axles forpulleys h, /Ll around whichpass metal cables z', 1 fitted with tensioning devices j, jl. Theseg cables are attached at each 'end to kears k, k1

YSecured in any convenient manner ill the angles formed between the longitudinal members a and the head and foot members al forming-:the lower frame @of fthe;bedstead.

It isf suioe'nt' to give a feW turnsto the tensioning devices y', jf to obtain the necesi-f sary tension of the CablsvlMWhicheareal*A ranged in the diagonal lines of the frame usoY rails and al vrCross-bar fom the side I:rails gall consttutedfio :tivo :channelled members ,t-
